Question
In each of the following number series, one term is
wrong. Find the WRONG term. 2, 6, 18, 54, 164, 486Solution
2 × 3 = 6 6 × 3 = 18 18 × 3 = 54 54 × 3 = 162 (but series has 164) 162 × 3 = 486 So every term should be “previous term × 3”. Wrong term = 164
A boat can cover 120 km in upstream in 4 hours and 144 km in downstream in 3 hours. Find the speed of the stream.
A boat can travel 30 km downstream in 45 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 3. How much time will t...
 A man can row the boat x km downstream and the same distance upstream in 12 hours. Also, he can row the boat 5x km downstream in 10 hours. At what tim...
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel a distance of 288 km upstream in 18 hours, ...
Speed of current is equal to 20% of speed of boat in still water. If the boat takes 4 hours to cover 120 km in still water, then find the time taken by ...
The speed of a boat is that of the current of water is 32:5. The boat goes along with the current in 3 hours 10 minutes. It will come back in
If the sum of upstream and downstream speed is 20 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 45 km in downward?
- A boat takes the same amount of time to travel (x – 24) km upstream as it takes to cover (2x – 84) km downstream. If the speed of the boat is 12 km/h a...
Speed of boat in downstream is 45% more than speed of boat in still water. If speed of stream is 9 km/h, then find the time taken by the boat to cover 8...
